Embodiment Construction

[0065]As shown in the figures, an iron-type golf club is generally designated 20. The golf club head 20 includes a body 21 having a front wall 22 with a recess 23 formed therein. Disposed in the recess 23 is a face insert 24 having a plurality of grooves 25. The body 21 is preferably composed of a material such as titanium materials, stainless steel, carpenter steel, 1020 steel, amorphous metals and the like. The material of the body 21 preferably has a density between 4 g / cm3 and 10 g / cm3. Such titanium materials include pure titanium and titanium alloys such as 6-4 titanium alloy, 6-22-22 titanium alloy, 4-2 titanium alloy, SP-700 titanium alloy (available from Nippon Steel of Tokyo, Japan), DAT 55G titanium alloy available from Diado Steel of Tokyo, Japan, Ti 10-2-3 Beta-C titanium alloy available from RTI International Metals of Ohio, and the like. The body 21 is preferably manufactured through casting. Alternatively, the body 21 is manufactured through forging, forming, machini...
